Hey, Gary. Thanks for contacting us. I recommend weighing your sash on a scale to confirm the best option. Based on your stamp, your sash may be 42 pounds, in which case either our 2970 or 2975 could work. The 2970 can carry sashes weighing 39 through 42 pounds, and the 2975 can carry 42 through 45 pounds. I would get the exact weight of the sash to be sure.
